Life is a marshmallow, easy to chew but hard to swallow.
It is a great happiness when men's professions and their inclinations accord.
Some books should be tasted, some devoured, but only a few should be chewed and digested thoroughly.
If we are to achieve things never before accomplished we must employ methods never before attempted
Wonder is the seed of knowledge
Things alter for the worse spontaneously, if they be not altered for the better designedly.
